How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 33 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to Adeniyikayodee/ng-postcode). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 0 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability75
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 708 tokens (~141/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management47
- Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
autocomplete_postcode Autocomplete a Nigerian postcode ~76
Suggest the next segment of a partly typed Nigerian postcode. Free. Use it while a user is still typing or only knows the start of their code. For a complete code, use validate_postcode, then lookup_postcode.

| Name | Type | Req | Description |
|---|---|---|---|
| latitude | number | yes | Latitude in decimal degrees, e.g. 7.6211. |
| longitude | number | yes | Longitude in decimal degrees, e.g. 5.2214. |

resolve_address Resolve a Nigerian address to a postcode ~218
Turn a described Nigerian address into a postcode, only as precisely as the evidence allows. A full building code comes only from a postcode written in the address, a location pin, or a landmark that is the address itself. Otherwise the result is an area or district prefix with a `question` for the user. Read the address yourself and fill `landmarks` and `geocode_queries`; the address text is sent to the configured geocoder.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The address exactly as the user gave it. |
| geocode_queries | – | – | Up to three map search strings you derive from the address: named places and streets with the town and state, most specific first, without directional words like 'back of'. |
| landmarks | – | – | Landmarks named in the address, each with how the address relates to it. Use 'at' only when the address is the landmark itself. |
| latitude | – | – | Latitude of a location pin the user shared. |
| longitude | – | – | Longitude of that pin. Give it with latitude. |
| Name | Type | Req | Description |
|---|---|---|---|
| code | – | yes | A full postcode at building level, else a prefix. |
| confidence | – | yes | – |
| evidence | array | yes | – |
| level | – | yes | – |
| method | – | yes | – |
| question | – | yes | What to ask the user to get a better answer. |
| status | string | yes | – |
No examples provided.
validate_postcode Validate a Nigerian postcode ~71
Check a Nigerian postcode's structure offline; return its canonical forms and segments. Free and instant. Does not confirm the code is assigned to a building; use lookup_postcode for that.
| Name | Type | Req | Description |
|---|---|---|---|
| postcode | string | yes | Code in any style, e.g. 'ek 01 a03 fk 01'. |
| Name | Type | Req | Description |
|---|---|---|---|
| compact | – | yes | Compact form for storage, e.g. EK01A03FK01. |
| error | – | yes | Why the code is malformed. |
| postcode | – | yes | Canonical form, e.g. EK-01-A03-FK-01. |
| segments | – | yes | – |
| spaced | – | yes | Form shown to people, e.g. EK 01 A03 FK 01. |
| suggestion | – | yes | A well-formed code if look-alike characters (O/0, I/1, S/5, B/8) were the only problem. Confirm it with the user before using it. |
| valid | boolean | yes | Whether the code is well formed. It may still be unassigned. |

What is the Nigeria Postcode MCP server?
Nigeria Postcode is an MCP server listed in the public MCP registry as io.github.Adeniyikayodee/ng-postcode. Validate, look up and resolve addresses to Nigeria's NIPOST digital postcodes (NDAPS). This page covers its PyPI package (ng-postcode-mcp).
Is the Nigeria Postcode MCP server safe to use?
Nigeria Postcode scores 87 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 17 October 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Nigeria Postcode MCP server expose?
Nigeria Postcode exposes 5 tools: validate_postcode, lookup_postcode, autocomplete_postcode, find_postcode_at_location, resolve_address. Their descriptions and schemas cost roughly 559 tokens of context every time the server is loaded.
Is the Nigeria Postcode MCP server still maintained?
Nigeria Postcode is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Nigeria Postcode MCP server under?
Nigeria Postcode declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
